Specification of Letters Patent. Patented B131. '7, 1916.

Application filed January 20, 1915. Serial No. 3,277.

ToaZZ/whom it may concern:

I 3e it known that I, T -inooonnDrrirans, a citizen of the United States, residing at Kansas City, in; the county of Jackson and State of M1ssouri,' have invented certain new I and usefulImprovements in Driving Mechanisin; and I do declare the following to be aqfull, clear. and exact description ofthe ina vention, such as will enable others skilled in the. art to which it appertains to make and companying drawings, and to theletters and figures of reference marked thereon,

- .which-form a part of this specification.

My invention relates to driving mechamsm for motor vehicles. and has for its ob- ]ect"to-prov1de mechanism whereby power maybe appliedto each of the wheels individually without interfering with the steering mechanism.

A further object of the invention is to .provide "driving mechanism wherein the universal joint is eliminated.

In accomplishing th'ese objects I haveprovided. the details of structure hereinafterdescribed and illustrated in the accompany ing drawings. wherein Figure-I 1s an. elevatlon of the axle,

wheels and driving mechanism mountedthereon, parts being in vertical sectipn. Fig. II 18 a plan new of the driving gearing and dlfi'erentlal gearing shown partly in section. Fig. III is a vertical section on the.

line IIIIII, Fig. 1, illustrating the revoluble mounting of the differential case.

Referring more in detail to the draw- -ings:l designates either the front or'rear axle of an automobile constructed according to my invention, and preferably of the.

I -beam type that is provided with knuckles 2 for receiving the vertical pins 3,- 'Revo;--

lubly mounted on the pins 3 are steering yokes 4, each provided with an upper and a lower yokearm 5-6 adapted for receiving the axle knuckle 2 and vertical pins 3. Integrally formed withthe yokes t are laterally directed spindles 7 which areprojected outwardly through central apertures 8 in disks are which the said yokes are rigidly bolted 1 or otherwise secured. The spindles 7 are provided with anti-friction members 10 and supported thereon are the wheels 11. The wheels 11 are preferablycast to form an integrally formed hub 1-;teand body portion 15,-

the latter having per heral flanges 16 on which is mounted a tire of any suitable mesh with theijdler-QG in orderthat power kind. Cast concentrically with the periphery of the wheel and forming a part of the body portion is an inwardly opening drum 18 withinv which the disk -9 is closely and revolubl fitted. Rigidl'y secured within an aperture 19 in the disk 9 is a bearing '20 within which is revolubly' mounted a stub shaft 21 which projects within the drum case and carries a spur gear 22 which meshes with a toothed band that is secured to the outer face of the drum by means of bolts 24. Mounted on the inner end of the stub shaft 21 is a bevel gear 25 that meshes with an idler gear 26 revolubly mounted on a shaft 27. The shaft 27 is sup ,ed in the standards- 31 and extending to the differential case presently described are drive shafts 36 which project into the socket members andcarry'gear wheels 37' which;

may be ap'pliedtoithe wheels;

In order that a, universal ported in vertical alinement with the pins 3 l joint-may be eliminated between the-motor and differ'en tial gearing 38, I providestandards-39lwitlr i in which the dift'erentialcase 40 maybe revo:

lublysupported; the said. case being reinforcedlby means of heavy bands 41 b'bltedf thereto and-which also; provide means for an extended bearing 43 for thefmain r ve. structing the parts a'universal joint is elimi- 2.

shaft 44. It will-be seen that by. so con nated between the differentiallgearing and each wheel and alsoby mounting the differ;

ential gearing-in a revolubly supported.case k f' v ferentangles without bindingo n' .athe gears-1 the drive shaft may be inclined at dif-Q' or other parts. Having thus by Letters-Patent, is:

1. The combination with an axle, of a knuckle pivotally mounted at each end of described my inventi omwha't .7 I claim as new thereinand des re to secure l 11o the axle, and provided with a spindle, a on each spindle,

wheel. rotatably amounted a rack fixed to the wheel, agear case above the knuckle mounting, the gear case concentrically with the knuckle mounting, a beveled pinion fixed on said shaft, a driving :shaft projected into the gear case, a beveled gear wheel on the driving shaft meshinggulith the gear wheel on thefirstnamedshaft, a driven shaft rotatable 1n the gear case, a pinion on said driven shaft meshing wlth the gear wheel on the first named shaft, and a gear wheel on theoppo- SItG endof the driven shaft nlBshlllgu-wltllthe wheel rack. a

2. The combination with an axle, of a knurkle pivotally mounted in each end of the axle and provided with a spindle, a ground wheel rotatable on the sp1ndle a rack on sald ground wheel, a spher cal gear case. mounted above the knuckle and com prising members, one movable within the yotherfan intermediate shaft mountedinthe gear case concentric with the with the wheel rack.

3. The combination with an axle, of a knuckle at each end of the axle, a. mnprvotally mounting each knuckle on the axle, a ground wheel rotatably mounted on each knuckle, a gear case over each, knuckle comprising a divided sphere having a stationary memberand a member movable within the stationary member, a driveshaft rotatably mounted in the stationarv. and spheric-al' member and provided with a pinion. a

shaft mounted in 'the case'concentrically with the knuckle'pin andlmving-a beveled gear wheel meshing with the drivin pinion, a shaft rotatably mounted in the movable spherical member and l'iaiinga pinion a shaft rotatable in on the movable a gear said shaft meshing With thewheel knuckle pivotally mounted at each end -of the axle and provided with a spindle, a

7 ground wheel having a cupped Web comprising a hub, a rackarranged horizontally within the Web and fixed thereto, a

plate fixedto the knuckle and inclosing the rack, a gear case mounted above the knuckle here, said movable'member having a bearngpro ected through sa1d-plate 1nt0 the webcup, a shaft rotatable in'said' bearing,

having a gear wheel meshing with said rack, a. drive shaft projectedintothe gear case, and gearing in said case operatively connecting the drive shaft with said first named shaft. i I

The combination with an axle, of a knuckle pivotally mountedin'each end of the axle'and comprising a spindle, a ground wheel having a cupped Web, a hub formed inte rally with the web and projecting inwardly and outwardly; therefrom, a disk fixed to the knuckle and lying: Within th jweb cup and spaced by the inner end of the hub, a rack "closed by the disl'g-a'g'ear case comprising stationary and movable members, a bearing member pro ected through the disk into the Web cap, a shaft rotatable .in the bearing and having a gear'wheel at one end meshing with said rack and having. a beveled pinion at the'opposite end, a shaft in said gear case, a beveled 'pinlon on saidshaft meshing with the plmon on the ,first named shaft, and a drive shaft-rotatable in the gear case and having a pinion meshing "with the gear; wheel on the case shaf. v 1
